The top eight teams from each region and the top two individuals not on a qualifying team will advance to the NCAA Championship May 20-23 at Tulsa (Okla.) Country Club.

The top-ranked Trojans have won three of the past six Pac-12 Conference championships but just tied for second there last week, finishing a shot behind Stanford. Still, the defending NCAA champs are the team to beat this season, having recorded eight victories and three second-place finishes.

“We are looking forward to regionals,” USC coach Andrea Gaston said. “We have some work to do to get ready. We still haven’t seen the best from our players.”

Five-time national champion Duke won its third straight ACC Championship a week ago and received its 22nd consecutive bid into regionals. The Blue Devils won the ACC title by 27 shots to collect its fourth tournament of the year, the most wins in a year for the school since they won five times in 2007-08.
